' WINDOW-FRAME SUPPORT.

Specification of Letters Patent.

Patented July 27, 1920.

Application filed February 17, 1920. Serial No. 359,291.

To all whom it may concern Be it known that I, EDWARD GELBKE, a citizen. of the United States, and resident of Jersey City,in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Vindow- Frame Supports, of which the following is a specification.

This invention relates to supports for attachment to house walls or window sills, or the like, and has for its main object the provision of such a device which will be practical and simple in operation and construction, and which will be readily set up for use or demounted for removal.

' porting bar for the same.

Fig. 3 is a perspective view of the block which provides the intermediate support between the said bar and the window frame, said bar being shown dotted and broken off.

Fig. 4 is an enlarged side view of my attachment in open or operative position.

Fig. 5 is an enlarged side view of said attachment in closed or inoperative position, adapted to be carried.

Fig. 6 is an enlarged underside plan view of said attachment, taken by looking in the direction of the arrow A.

Referring now in detail to the drawings, the numeral 1 represents the wall of a building, and 2 the window frame thereof. The customary runner or tracks of said frame in which the windows slide are indicated at 6. I provide a block 3 with one or more vertical grooves 4 adapted to engage one or more of said runners 6, and thereby to be secure against any force tending to withdraw said block outward from the window. As is clear in Fig. 1, one of said blocks is mounted in each lower corner of the window frame. Each of said blocks contains also a recess 5, substantially right-angled, so as to provide a shoulder against which a bar 7 may rest, and thereby to prevent forward motion of said bar, that is, motion thereof outwardfrom the window. This bar is se cured at each end in one of said blocks.

Said bar is provided with lateral grooves 8 and 9 which are provided with angular bases, as indicated in Fig. 2. It is in said angular basesthat the devices indicated generally by 10 in Fig. 1 are securely held.

Each device or attachment 10 comprises a main frame composed of two vertical parallel members 11, a rod 13 joining their upper ends, and a rod 13 joining their lower ends; the latter is similarin all respects to the former. Stationary nuts 15, washers 12, and adjustable nuts 14 are provided as shown to hold said vertical members se curely to said rods 13 and 13*. A pair of parallel members 16 are pivotally mounted on the rod 18, and are provided at their ends with angular recesses adapted to engage said angular bases of the grooves 8 and 9. An auxiliary bar 22 braces these latter members and is attached near the ends thereof. A bracket member 17 is pivotally attached at one end to said member 16 and at the other to the member 11, so as tohold said members 11 and 16 apart as shown in Fig. 1; bolts and nuts 18 and 19 are provided for this purpose, and the former may be removed to allow the bracket 17 to be folded inward into practical coincidence with the member 11.

A bar 21, similar in all respects to the bars 13 and 13", is bridged between the members 11 at about midway of their length. A platform or board 20 rests its end on said bar 21, and the former is clamped to the latter by means of a grooved plate23, ties 24, and screws thus said platform is adapted to rotate about said bar 21. At the free end of said platform 20 a plate 26 is secured by means of screws 27, and holes pass therethrough, as well as through the platform for the passage of the ends of cables 29. These cables are suspended from the rod 13, one on each side, and a knot 28 is tied in the lower end of each so as to hold the end of said platform in a horizontal position.

Near the lower ends of the vertical frame members 11 are pivotally mounted wall supports 80, which, when the device is in use,

rest their ends 32 against the wall of the building and thereby retain the device 10 in the position shown in Figs. 1 and 4. Stops or lugs 33 are provided on the lower ends of the members 11 to limit the lower position of said supports to such a degree that the platform 20 will lie horizontally, and the members 11 vertically.v

When the device is being transported, it is folded or collapsed into the position shown in Fig. 5, by removing some of the nuts. The manner of collapsin the device is readily apparent from the illustrations. WVhen the device is collapsed, the same is carried about by taking the bar 13 in the hand. i

As illustrated in Fig.1, two of the abovedescribed devices may be attached to a window frame, and a platform or board 31 supported upon them, thus affording a scaffold or the like upon which one may stand.

I claim: f

1. A' device of the class described comprising vertical supporting members, a plurality of horizontal rods secured between said members, a platform rotatably mounted upon one of said rods, cables attached to the uppermost of said rods and to the ends of said platform, and means for attaching the device to the wall of a building.

2. A device of the class described, in combination with a window frame and the wall of a building, comprising parallel vertical supporting members, a plurality of horizontal rods secured between said members, a platform rotatably mounted upon one of said rods, cables attached to the uppermost of said rods and to the end of said platform, bracket members pivotally attached to the upper ends of said vertical members, additional bracket members attached to said vertical members and to said first named bracket members, the latter having angular recesses in the ends thereof, blocks adapted to be retained in the said window frame, a bar having angularly-based recesses therein, means in said blocks for retaining said bar,

said first-named brackets adapted to be secured to' said bar, said angular recesses adapted to engage said angularly-based recesses, additional supportingmeans pivot ally attached to the lower ends of said vertical members, and stops on said vertical 1 members for limiting the rotation of said additional supporting means.
